We mean a principle of sympathy, not of hostility; of union, not of separation. We mean a feeling of common interest among those who live under the same government, and are contained within the same natural or historical boundaries. We mean, that one part of the community shall not consider themselves as foreigners with regard to another part; that they shall cherish the tie which holds them together; shall feel that they are one people, that their lot is cast together, that evil to any of their fellow-countrymen is evil to themselves, and that they cannot selfishly free themselves from their share of any common inconvenience by severing the connexion.
—John Stuart Mill
